DES performs a 5000 square degree survey of the southern sky in five optical bands (g,r,i,z,Y) to a depth of ~24th magnitude. Contemporaneously, DES performs a deep, time-domain survey in four optical bands (g,r,i,z) over 27 square degrees. DES exposures are processed nightly with an evolving data reduction pipeline and evaluated for image quality to determine if they need to be retaken. Difference imaging and transient source detection are also performed in th","authors_text":"A. Benoit-L\\'evy, A. Drlica-Wagner, B. Yanny, C.-C. Ngeow, C. Pond, D. A. Goldstein, D. Gruen, D. L.
